Product details
Overview
MAX4532CWP+ from Maxim Integrated is a low-voltage CMOS analog switch IC configured as three independent single-pole/double-throw (SPDT) switches, operating from ±2V to ±6V dual supplies or +2V to +12V single supply, with 150Ω max on-resistance, 8Ω max channel-to-channel on-resistance matching, and rail-to-rail signal handling - used in precision audio-signal routing and battery-operated test equipment.
For engineers reviewing the MAX4532CWP+ datasheet, MAX4532CWP+ pinout, MAX4532CWP+ application, or MAX4532CWP+ equivalent, this page delivers verified electrical specs, package-confirmed pin functions, real-world use cases, and two validated alternative parts for design-in flexibility under industrial temperature and low-power constraints.
Technical Context
The MAX4532CWP+ implements three fully independent SPDT switches with complementary enable inputs (EN1/EN2), address latching via LE, and 3-bit address decoding (ADDA/ADDB/ADDC) to select one of eight possible switch configurations per section. Each switch supports bidirectional analog signal flow with no intrinsic directionality between NO_, NC_, and COM_ terminals.
It features break-before-make switching (tBBM = 4–10ns typ), <1.5pC charge injection, and >2kV HBM ESD protection. Logic inputs are TTL/CMOS-compatible across its full supply range, with thresholds scaling from 0.8V/2.4V at +5V to ~3.1V high threshold at +12V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Configuration | Three independent SPDT switches (COMA/NOA/NCA, COMB/NOB/NCB, COMC/NOC/NCC) |
| Supply Range | ±2V to ±6V dual or +2V to +12V single - enables operation in low-voltage portable systems and bipolar instrumentation |
| On-Resistance (RON) | 150Ω max at +5V supply - ensures minimal signal attenuation and gain error in precision analog paths |
| On-Resistance Matching (∆RON) | 8Ω max between channels - critical for matched gain/phase in differential or multi-channel routing |
| Off-Leakage Current | 1nA max at +25°C, 50nA max at +85°C - preserves accuracy in high-impedance sensor or DAC output interfaces |
| Switching Speed | tON = 150ns, tOFF = 120ns at ±4.5V - supports multiplexing of audio and medium-speed data signals up to ~1MHz |
| Rail-to-Rail Signal Handling | VCOM/VNO range = V− to V+ - allows full-swing AC/DC signals without clipping or distortion |
Pinout & Package
MAX4532CWP+ is housed in a 20-pin wide SO (Small Outline) package (SOIC-W), 7.5mm body width, 1.27mm pitch, RoHS-compliant, with exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply input | Powers analog switches and internal logic; sets upper analog signal limit (VCOM/VNO ≤ V+) |
| V− | Negative supply input | Powers analog switches; sets lower analog signal limit (VCOM/VNO ≥ V−); connect to GND for single-supply use |
| GND | Digital ground reference | Reference for logic inputs (ADDA/ADDB/ADDC/LE/EN1/EN2); isolated from analog signal path |
| LE | Address latch enable | Edge-triggered control that captures ADDA/ADDB/ADDC state to configure switch routing |
| EN1, EN2 | Complementary enable inputs | Active-high and active-low enables per switch group; both must be asserted for conduction |
| ADDA, ADDB, ADDC | 3-bit address inputs | Select one of eight switch states per SPDT section; ADDC not used in MAX4531 |
| COMA, COMB, COMC | Common terminals | Center pins of each SPDT; bidirectional - may serve as input or output |
| NOA–NOC, NCA–NCC | Normally-open / normally-closed terminals | Paired with respective COMx; NOx closed when selected, NCx open; fully interchangeable |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog SPDT switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4532EWP+ | Same functionality and pinout, but rated for −40°C to +85°C industrial temperature range vs. 0°C to +70°C for MAX4532CWP+ | Suitable for extended-temperature environments (e.g., outdoor test gear, engine bay sensors) | Select MAX4532EWP+ when operating beyond 70°C ambient or requiring AEC-Q200 alignment |
| ADG1434BRUZ | Quad SPDT, 4.7Ω typical RON, ±15V supply capable, but no address latching or EN1/EN2 complementarity | Lacks integrated address decode and latch; requires external logic for multi-channel sequencing | Choose ADG1434BRUZ only if ultra-low on-resistance (<5Ω) and higher voltage swing (>±6V) outweigh need for embedded control logic |
Compared with MAX4532EWP+, the MAX4532CWP+ offers identical performance at lower cost for commercial-temperature applications, while ADG1434BRUZ trades integrated control for lower RON and wider voltage range - making it suitable only where external sequencing is already implemented and precision voltage handling is paramount.

FAQ
What is the maximum supply voltage for MAX4532CWP+?
The MAX4532CWP+ supports absolute maximum ratings of V+ up to +13V and V− down to −13V, but its specified operational range is ±2V to ±6V dual supply or +2V to +12V single supply. Exceeding ±6V or +12V risks permanent damage, and operation above these limits voids parametric guarantees - always observe the Absolute Maximum Ratings table in the datasheet for safe design margins.
Does MAX4532CWP+ support single-supply operation with V− tied to GND?
Yes, MAX4532CWP+ fully supports single-supply operation: tie V− to GND and apply +2V to +12V to V+. All analog signals (VCOM/VNO) then swing from 0V to V+, and logic inputs remain compatible. At +3V supply, RON rises to ~600Ω, and switching speed degrades - verify timing and on-resistance in your specific V+ condition using the Typical Operating Characteristics curves.
How does the address latching (LE) function work in MAX4532CWP+?
The LE (Latch Enable) input is edge-sensitive: a rising edge captures the current logic states of ADDA, ADDB, and ADDC, freezing the switch configuration until the next LE pulse. This decouples address updates from switching action, eliminating glitches during address transitions - critical for synchronous routing in microcontroller-driven systems. LE operates independently of EN1/EN2 enables.
Can MAX4532CWP+ handle bipolar analog signals like ±2.5V?
Yes - when powered with dual supplies (e.g., V+ = +5V, V− = −5V), MAX4532CWP+ supports rail-to-rail analog signals from −5V to +5V. A ±2.5V signal falls well within this range and experiences full linear conduction with no clipping, provided the signal never exceeds V− or V+. The device's CMOS architecture inherently supports bidirectional, symmetrical analog conduction.
Is MAX4532CWP+ pin-compatible with the 74HC4353?
Yes, MAX4532CWP+ is explicitly designed as a pin-compatible, functionally enhanced replacement for the 74HC4353. It shares identical 20-pin SO footprint, pin assignments for V+, V−, GND, EN1, EN2, LE, ADDA–ADDC, and all NO_/NC_/COM_ terminals. Unlike the 74HC4353, MAX4532CWP+ adds rail-to-rail operation, lower leakage, and improved ESD protection - enabling direct drop-in upgrades.
